wear block meaning in Chinese

磨损量块

I gazed long at the weather - worn block , and , stooping down , perceived a hole near the bottom still full of snail - shells and pebbles , which we were fond of storing there with more perishable things ; and , as fresh as reality , it appeared that i beheld my early playmate seated on the withered turf : his dark , square head bent forward , and his little hand scooping out the earth with a piece of slate
我对这块被风吹雨打的岩石盯了很久又蹲下来，看见靠近地底下那一个洞，仍然装满了蜗牛和碎石子。这些东西以及另外一些容易消灭的东西都是我们喜欢储藏在那儿的。而且，像现实一样地鲜明，我好像看见我早年的游伴坐在那干枯的草皮上。
